This study was carried out to examine changes in the quality characteristics of Aralia continentalis Kitagawa (AcK) Jangachi made with different $CaCl_2$ and seasoning treatments during storage at $4^{\circ}C$ for 6 months. The results exhibited there were no significant changes in pH, acidity, and salinity in the various samples. The numbers of total bacterial counts and lactic acid bacteria increased slowly during the early storage period and then increased rapidly in the third month. In the fifth month they reached their highest level near $6.6{\times}10^{6}cfu/ml$ and then decreased thereafter. The sample treated with $CaCl_2$ exhibited a higher degree of hardness than the untreated sample. Finally, the sensory characteristics of the AcK Jangachi were highly acceptable during the entire storage period in terms of color, smell, bitterness, texture, and general preference regardless of the $CaCl_2$ treatments.

Chemical accidents are the cause of the accident site during the initial responders to quickly and easily see materials and concentration method for the U.S. Environmental Protection Agency(EPA) is widely used in the initial response team direct reading detection equipment used. Ministry of the tubular gas detection equipment to detect direct reading detection equipment used in the event of an accident scene, and shell-and-tube gas detector for rapid detection and identification and precise analysis of causative pollutants before about strategically can identify the quantitative and qualitative useful equipment. However, those who initially respond to the scene of a direct reading detection equipment and a simple lack of understanding of how to use the numbers only because of the way you want to check the accuracy of detection results have been raising questions about the increase. The scene of the accident in order to obtain an accurate detection results used in this paper, the Ministry of Environment of gas detectors detect tubular Kitagawa and Draeger detector tube to check the reactivity of the material on-site detection of early response of those who were to raise the accuracy of the results.

This study investigated the anti-inflammatory effects of mixed extracts of Achyranthes japonica Nakai (Aj) and Aralia continentalis Kitagawa (Ac) (ratios of 1 : 2, 1 : 3, 1 : 5, 2 : 1, 3 : 1 and 5 : 1) on RAW264.7 macrophages. Cell toxicity was determined using a cell counting kit (CCK) assay. We evaluated anti-inflammatory effects of the mixed extracts of Aj and Ac by measuring interleukin $(IL)-1{\beta}$, IL-6, and tumor necrosis factor $(TNF){\alpha}$ using an enzyme-linked immunosorbent assay (ELISA) kit assay. The mixed extracts of Aj and Ac inhibited lipopolysaccharide (LPS)-induced $IL-1{\beta}$ and $TNF{\alpha}$ in LPS-stimulated macrophages. Comparing different ratios of the mixed extracts, the 2 : 1 ratio of Aj and Ac has much more potency and inhibited the production of $TNF{\alpha}$ in LPS-induced RAW264.7 cells. The results of the present study showed that the mixed extracts of Aj and Ac have potential anti-inflammatory effects on RAW264.7 macrophages. Therefore, these extracts may be used as a good source of functional foods for the protection against inflammatory diseases.

We investigated the anti-inflammatory activities of various organic solvent extracts with and without Lactobacillus plantarum fermentation of Aralia continentalis Kitagawa which has hypotensive effects in addition to excitatory effects on the central nervous system. It has been used to treat arthritis, colds, neuralgia, rheumatism, and itchy skin. Our extracts were tested for their anti-inflammatory potential on NO production and the expression of inflammatory factors in lipopolysaccharide-stimulated RAW264.7 macrophages. Extracts with and without L. plantarum fermentation were prepared using water, ethanol, hexane, ethyl acetate, and butanol. The RAW264.7 cells were tested for toxicity and the anti-inflammatory activity of each extract was determined at a concentration with no toxicity to the cells. The extracts used in this study significantly inhibited both the production of NO and the mRNA expression of COX-2 and iNOS, the major inflammatory factors. The production of inflammation-related cytokines $IL-1{\beta}$, IL-6, and $TNF-{\alpha}$ was also significantly reduced. These results suggest that the extracts involving fermentation by L. plantarum can inhibit cytokines by controlling the expression of inflammatory cytokine genes. It is considered that the water, ethanol, and butanol extracts after fermentation with L. plantarum could be useful as functional natural materials with anti-inflammatory effects.

Analysis of evacuation routes for traditional buildings is important. In this study, we considered the evacuation routes using the probability of building collapse and analyzed the open space of traditional town. We considered evacuation routes from traditional houses to designated refuge places, and analysis the relationship of open space and evacuation routes.

Over 5lm/W white luminous efficacy was obtained by 11" color test panel with narrowed discharge electrodes combined with high Xe partial pressure. By using optical spectroscopic methods, it was suggested that the electron heating efficiency is the most significant to improve the plasma efficiency in our experimental conditions.
